  Toxoplasmosis caused by the protozoan Toxoplasma gondii is a major public health problem,infecting one third of the world human beings,and lead to abortion in domestic animals.A vaccine strategy would be ideal tool for improving the disease control.Many efforts have been made on development of vaccines against T.Gon dii to reduce oocyst shedding in cats and tissue cyst formation in mammals over the last 20 years,but only a livEattenuated vaccine based on the S48 strain has been licensed for veterinary use.We here review the recent deve lopment ofT.gondii vaccines in cats,food:producing animals and mice,and present its future perspectives.Ho wever,a single or only a few antigen candidates revealed by various experimental studies are limited by only eliciting partial protective immunity against T.gondii.Future studies ofT.gondii vaccines should include as many CTL epitopes as the live,attenuated vaccines.

本研究目的是对河南省猪弓形虫病作分子流行病学调查及确定其基因型.从河南省各个地区采集病猪的组织病样品1647份,用我实验室建立的扩增弓形虫B1基因的PCR方法来检测,检测到31份为阳性.猪弓形虫病阳性感染率为1.88%(33/1647).为了确定这31株弓形虫分离株和本实验室以前保存的3株河南省猪源弓形虫分离株的基因型,我们应用了基于5个微卫星位点(B17,B18,TUB2,W35,和TgM-A)
本研究选择了北京和沈阳的4个规模化奶牛场,间隔8个月进行全群牛的3次采集血样,采用SPA-ELISA检测血清抗体,统计牛群弓形虫抗体阳性率及个体牛抗体滴度的变化,并结合奶牛的年龄、怀孕次数、流产发生史等因素综合分析研究.结果如下:(1)所选4个牛场牛群弓形虫血清抗体阳性率在3次检测中处于一定的变化之中,个体牛的抗体滴度处于变化之中,但3次之间的变化无明显可循的规律.(2)将检测结果与牛场档案资料进
